EAS service/process crashing

We've been experiencing some intermittent crashes of the HyS9eas.exe process and service. Specifically there is a windows event: "Faulting application HyS9eas.exe, version 1.0.0.2, faulting module jvm.dll".

We're running v11.1.1.3 (no patches), Weblogic v9.2 app server and there isn't a specific cause that seems to kill it. We've had about 3 crashes over the last couple of months and starting the service up again is fine and it could run for weeks without issue.

I have two thoughts:
1. Try adding a java min/max memory parameter to the start-up (i.e. the registry parameters for EAS), although I'm not sure what values to try - 1/2 GB or 1GB?
2. Add another step to my nightly essbase backup process to re-start EAS as well as essbase.

Both are a good start. We've added the JVMOption<n>'s past the default (-Xms1024m and -Xmx1024m) . I forget if they're there by default, so check your JVMOptioCount if you need to add JVMOptions. I've heard that establishing the min to be the max was recommended, but I have no proof. Re-starting EAS has helped us after a large number of business rules are run/updated during a business day. We re-start twice a week in 11.1.1.3 (was every evening inder 9.2.0.3).
